Answer:
840
Step-by-step explanation:
120 is 40% of 300, and 840 is 40% of 2100 is 840.
First distribute the 2, then add 7 to that side, so you have 2g+17=-4g+g , subtract 2g and it should be easy to find from there lol
460/12 = 33.3 so about 32 trays if the smallest and 33 as the answer but best would be 33
Since arc CD is 100 degrees, the rest of the circle must be 260 degrees. Since the rest of the circle is made up of two equal arcs, then arc BC must be half of 260 degrees. Thus, the answer is 130 degrees, C.
